.23B+.286C-.23D=0
-.69B+.429C+.31D=0
.69B+.857C+.92D=4

To solve the system of linear equations:

\[
\begin{align*}
0.23B + 0.286C - 0.23D &= 0 \quad \text{(Equation 1)} \\
-0.69B + 0.429C + 0.31D &= 0 \quad \text{(Equation 2)} \\
0.69B + 0.857C + 0.92D &= 4 \quad \text{(Equation 3)}
\end{align*}
\]

We can solve this system using methods like substitution, elimination, or matrix techniques (e.g., Gaussian elimination). I'll use matrix techniques to find the values of \( B \), \( C \), and \( D \).
